A.A Math 7B Oct 11 Big Idea: Observation and description of changes in the world around us are the first steps in finding and learning about patterns. INV 5 Essential Question: How can a graphing calculator help me to discover relationships between variables?
5.2 A 1 Use your calculator to make a table for the equation y=3x
2 Copy part of the calculator’s table onto your paper

3 Use your table to find y if x=5
If x=5, y=15
B 1 Use your calculator to make a table for the equation y=0.5x+2

3 Use your table to find y if x=5 If x=5, y=4.5
5.2 Follow-Up
1 Use your calculator to make a table for the equation y=3x. Describe the graph The graph is diagonal and pretty steep
2 Use your calculator to make a graph for the equation y=0.5x+2. Describe the graph The graph is not steep, it's closer to being flat. it starts at 2 in the third quadrant, goes through the first, ends in second 3 How do graphs 1 and 2 compare The Y=3x graph is steeper than Y=0.5+2
4 How would you make a graph for the equations y=3x and y=0.5x+2
I would first make a table of the information then create a graph out of it
